i'll make a few generalised statements:
1) if you are using windows 8 I would assume that your laptop is a fairly recent model using fairly recent hardware which means it is likely to support the higher speeds
2) the wireless on the shub 1 is very bad and pretty much any new router you buy is going to have better wireless than shub 1
3) that being said, there are many factors which affect wireless throughput so don't expect to go out and buy a proper router and think it is going to give you 100/6 all the time
I'll do my router recommendations tomorrow morning because I am way too tired to give my fan boy speech atm, my poor eye lids are closing
